validation for Gridnumeric column

[NVB]

I  have about 4 columns in RADGRID which I am defining as GRIDNUMERICColumn with following
 

<telerik:GridNumericColumn DataField="AMT1" UniqueName="AMT1 HeaderText="Amount1" 

DataType="System.Int32" DataFormatString="{0:N0}" DecimalDigits="0"

 

ForceExtractValue="Always" SortExpression="AMT1" AllowFiltering="false" EmptyDataText="0"

 

Aggregate="Sum" FooterAggregateFormatString="{0:c0}" FooterStyle-HorizontalAlign="Right" >

 

<ItemStyle HorizontalAlign="Right" />

 

</telerik:GridNumericColumn>

Also I have to total column next to it as  GridCalculatedColumn

AMT1   AMT 2  AMT3   AMT4    TOTAL

I nee to attach  a validator ( client and Server )  to validtate that in edit mode the when user enters the amounts , it should give message if the total goes negative .

As of now i am handling  programmtically when updating I am reading the values and giving message below the grid that there is error . This may be not a efficinet way and this has lot of limitations when i am multirowedit

Can you pleas tell  how to do  client side validation and  server validitaion ( custome validator)

Thanks for your help

Hello Vemula,

In order to achieve your scenario you could take a look at the demo and help article provided below. Additionally, client-side validation is not a trivial implementation but you could implement custom JavaScript logic in order to calculate the values from the RadNumericTextBox controls and if the value is bigger than the expected you could show the message to the user.
